Humm, there is a way, but it is C code and it is not really clean:
/* Change language. */
setenv ("LANGUAGE", "fr", 1);
/* Make change known. */
{
extern int _nl_msg_cat_cntr;
++_nl_msg_cat_cntr;
}
(from the gettext manual:

No problem.

Well, the avantage of camomile is that you can produce full ocaml native
application (almost without C binding). The only other advantage, is not
really "external developper" visible: it is a little bit cleaner because
you have better control of thread unsafe variable. But it is not an
issue, both implementation should work well.
Kind regard
